Answer:
C) x = 12
Step-by-step explanation:
We can calculate the value of x using similarity ratio
x/8 = 9/6 cross multiply expressions
6x = 72 divide both sides by 6
x = 12
Answer:
f-1(x) = (x-8)/2
Step-by-step explanation:
f(x) = 2x+ 8
y = 2x + 8
replacing y and x
x = 2y + 8
2y = x- 8
y =( x-8)/2
f-1 (x) =( x-8)/2
2x^2 + x -3 can be factorised
<span>[2x + 3][x - 1] </span>
<span>As length times width = area </span>
<span>one possible set of measurements are </span>
<span>length = [2x + 3] </span>
<span>width = [x-1] </span>
You cant if you are trying to figure out what the factors are
